Fig. is v:in enhirged sevlionid View ol' one of the tuhes of the heutingwoils, showing thv wire coil in section. Fig. 3 is a longitudinul ser-tion of si inodilied forni of construction. Fig. 4 is ii transverse rertimil sertion of Fig. :i on the lines 4 4.

lnstond olii wire-coil ohstrurtionl may use another forni, such iis shown in Figs. 3 und 4, wherein hars "2, having ineiined dash-pintas 2i .31 iov-ted upon the sinne, are plurali in the hottoiu of the tuhes I6 16, the )lates .21 heing inrlined in the direction o flow of the liquor, ln holh vonstrurtions the liquor, regi: rdlvss of its ronvvntrution, will he dashed up hy thv uirv ohstrurtions 15 or the pluies 2i toward the (op und uriner portion of the tnhv, thus lli-ingingr the iqnor into t'onluvt. with thv entirv headed sin'fure of the voils or tuhrs, 'ihv tvndonvy to strnliiieution und iniperfvvi :it-tion muy thus he prevented when the evaporator is run under ordinary renditions wit h :i sun-ill feed-opening supplying the liquor to the tuhes of comparative y isrge diunietvr. By this eonstruetion also the cent1-.d und hnger portion of the tube is left open und free lorthepussngeef the vapor, so that it hss :i free passage throufh the eoil lo the outlet. und hence does notriessen the rsoidily ol motion of the liquor through the rod.
